What would you recommend? to use "UpdatePanel" or "calling the webservice" since with both of them you can do samething.... which one is more efficient? Takes more resources?

Thank you.

This seems to be working in 'Web Site' type of projects. However, in 'Web Application' type of projects, it is poping "WebService is undefined" error. Any ideas?

I'm trying to retreive the image frames from IP camers. I have used your examples using update panel both using timer and using javascript. Both both work fine except replacing the image produces a flicker. I tried using the Webservice approach (I'm using VS 2008) the WebService is implemented differently from VS 2005 and has the

<System.Web.Script.Services.ScriptService()> _ included but commented out by default. uncomenting it and invoking the service returns correctly. However WebService.GetUpdate(OnComplete, OnTimeout, OnError);

fails returning "Microsoft JScript runtime error: 'WebService' is undefined".

1. can the flicker be iliminated in the "UpdatePanel" approch?

2. what is the solution to the WebService call from aspx in hte same project?

Thanks.

Thanks for this video. But sadly, i created an application in exactly the same way you are. For me i am getting Object Not Found error from javascript. I downloaded your C# code file. They are fine. I can't figure out what went wrong. any possible reasons? i event user the ScriptServices tag, but still. Btw how can i attach my solution for checking?

I got it working just fine, but I don't want to use body onload because the page element being populated is inside of a login view.
